I have a Verizon Trophy that has been GSM unlocked (I use it on ATT). After a factory reset, CDMA mode is my only option. I can't even find a way to enter the unlock code again. Is there a way to re-enable GSM mode? Thanks in advance for any help
nevermind. I fixed it by flashing a custom rom on it. I still don't know why it was only cdma after the factory rest.

Where you using a default Verizon factory rom? That's just plan weird. The default option should always be Global Mode unless the SIM Card wasn't seated correctly.
yeah it was the original firmware. It happened after a factory reset. The option under cellular settings would not change to anything other than cdma. it possibly could have been related to the sim card. Who knows? I guess it just gave me a reason to flash a new rom.

Hello. Tell me please what ROM you use to unlock GSM?
Thank you!
Hey guys
I was out shopping tonight and the weirdest thing happened to me. My data stopped working. I realized it when I was trying to make a phone call.
I toggled airplane mode on and off "nothing"
Power cycle "nothing"
Reset back to factory settings while on pure nexus rom "nothing"
Unrooted and flashed stock factory image and you guessed it. Still no dice.
Weird thing is that when I put my sim card in my note 5 it works fine.
When I put my wife's sim card, she's with another provider, in my nexus 6P it works with the exeption of LTE. For some reason when I put another provider's SIM card LTE doesn't work.
I bought my phone off of Kijiji so I'm not sure I can call google for an RMA.
It's just weird that my sim card work fine with another phone and that another sim card works on my phone.
I'm stumped guys.
Any suggestions?
did you try reflashing the radio from fastboot?

Doesn't flashing factory image take care of the radio too?

Yes the radio is in the factory image, if you did it manually it's possible you forgot the radio.img. If you bought the phone used it's possible it has been reported stolen or the previous owner stopped making payments. That's all I can think of, also make sure your APN is absolutely correct for your provider.

It was working just fine until last night. I flashed the whole factory image, radio included. It works with a SIM from a different provider. No LTE though.
Hello, the phone on firmware APF2. Menu there are no hotspot. My opeator not a sprint, your phone is connected to another operator. Sim card and not a sprint, and from another operator.
How to make a hotspot to display the menu?
Well, from that message it sounds like your SIM card is not a sprint one. Who is your service provider? If it not sprint I would suggest using the unlocked firmware G935U. If you are with sprint I would try possibly a factory reset or take out the SIM and reinsert it. If it is still not working re-flash the pf2 firmware.
My GSM operator www.orange.md and CDMA (Number prescribed in the phone itself.) www.idknet.com.
I've tried to do is reset to factory Adapting and twice pierced him. Hotspot Menu appears.
You can easily sew G935P firmware from G935U? Problems will not be? Do I get bricks, blocks?
I haven't tried my self yet, but there is a whole thread talking about the unlocked firmware and using it on a print phone. You should take a look.
ok
I moved my T-Mobile SIM card from my Nexus 6 to my never used, eBay purchase, 6p. The 6p does not detect the SIM card. I reinserted it multiple times with no luck. I don't know if it matters that I installed TWRP, Nitrogen ROM and Franco kernel, without the SIM in the phone?
The phone is otherwise fully functional.
Any ideas on what might be going wrong? The package slip that came with the 6p states, "Tested for Key Functions, Ready for Resale". I've contacted the seller for advice.

Probably should of checked it out before loading a custom ROM. That being said if the ROM is 8.0 I don't think the first version of the update is compatible with T-Mobile.
"8.0.0 (OPR6.170623.013, Aug 2017, Not for TMO/USCC/Fi)"
You should maybe try a stock ROM first. Get nexus root kit. There is an option to revert the phone back to stock. Might help.
Just a shot in the dark. May also be locked to a region. Good luck though.
I reinstalled stock Oreo. Now, I'm only seeing "No Service". I don't know if this is of significance, but when I check Settings - > System - > About phone - > Status, SIM status everything is blank. At least the SIM was detected. I didn't realize when I installed stock Oreo it would wipe out my SDcard.
The vendor image is used with Nitrogen was opr5.170623.007.img.
And I suppose the sim works in other phones?
It's hard to say what is going on. May just be in backwards?
Aside from the bootloop and battery issues the 6p has been awesome as far as loading ROMs. You never have to replace the bootloader so even if you break the recovery it can be fixed easily. Not the same for my sapphire unfortunately.
Anyways I would first say it may be a physical issue, Especially if the sim says it's blank. Again, good luck.
I believe it's just Android 8 and not the phone. Go through any 6p Oreo thread and will find one person with this problem. Solutions that where posted fingerprint/pincode security off before flashing, no encryption on first boot and solution that worked for me complete wipe of phone flashing stock Oreo. I haven't heard any direct answer on what the cause is and I think the first 2 solutions worked for people because they did a clean flash of stock Android 8 anyways.
Yes, the SIM works fine in my Nexus 6. I noticed under SIM status, it lists "No signal".
I installed the factory Nougat ROM and still no service.
Under SIM status in Settings, Network is Unknown, Signal strength is 0, Cellular network type is Unknown and Service state is Out of Service.

Is your IMEI field blank too in Settings? If the phone does not have an IMEI, the device may have corrupted EFS partition(s). Boot the device to bootloader (fastboot mode) and select "Barcodes". Is your IMEI there? Is your model a H1511 (US model)?
Put a known working SIM in the phone from a different carrier (preferrably not an MVNO), If that doesn't work, since your phone is new (to you) there is no harm in fastboot formatting these 3 partitions (system, cache and userdata) and then using the Google script (batch file) that comes with a full factory image. Not a factory reset, not manually flashing a ROM. One other possible scenario is that if the phone was previously used on ProjectFi, you may need to contact Google and have your phone's IMEI de-registered. Hopefully you get it working and won't be forced to return the phone.

Barcodes shows IMEI present and model is H1511. I ran the script in the full factory image for Oreo and then tried the same with Nougat. I didn't reformat the partitions prior to flashing ROM. Is this important or does the factory image replace them anyways?
I don't have access to another carriers SIM card.

The script uses fastboot erase which does not format the partitions. Formatting returns partition information, any errors and in some cases corrections. You did not mention IMEI within settings, both under "SIM Status" and "IMEI information". If present in bootloader, but not in settings, this may further point to a SIM card. Until you try (borrow) another carrier's SIM for 5 minutes you won't know for sure. At the very least you could get TMo to provision you new SIM. They should not charge you for this, and it may change your situation. There are many threads on this very same topic. Maybe searching those would give you another idea.

According to Google, the phone was purchased from them. They do not know if the phone is financed, as this would cause the IMEI to be locked. I'll try the T-Mobile store next.
Spent an hour at T-Mobile. The sales rep was determined to fix it, but in the end was unsuccessful. The Ebay seller issued an RMA and I dropped off at the P.O.. Will try getting another.

No, I meant the the Google-Fi the MVNO (carrier) not finance. If the phone was activated on Fi, it will have to be de-registered on their end. You still did not reply about IMEI present or not in Settings>>Sim info?

When I went into Settings, the IMEI was present, but no carrier information. The phone recognized the SIM card, but that was all.
In the chat session with Google Support, I did ask about Google-Fi and she wrote that she was unable to provide any information on that. She said the only information she could provide is where the phone was purchased.
I came across the same issue. Just flash your vendor.img using flashfire, this will fix everything.
Another fix for the no sim is too turn off security pin lock and reboot the phone. I take no credit for this find just spreading the good word. ?

Thanks so much. Worked like a charm and could then reenable pin lock and reboot and SIM kept working.

could you detail how to do just that? Because I'm in Brazil and I have the same problem.
I bought used S8 that had clean IMEI (not blacklisted), it was locked on Sprint and with financial eliglibity. Before I got it unlocked it didn't recognised any sim card, after unlocking it did regular setup on my ATT card with all the ATT apps but it doesn't have service. Then I tried with Verizon SIM and it did the same, regular setup but no service. What do you think what's the problem ?
Phone build number : R16NW.G950USQS3CRE2
Is it rooted, and if it is, have you uninstalled any system packages
If not, try a factory reset and making sure the sim is active and APN settings are working and you have chose a network

It's not rooted, I did remote unlock with unlocking service and they flashed original firmware on it, nothing should be messed up.
I did factory reset few times as well as network reset. I double checked APN info and ofc it's setted up together with card.
I forgot to mention that phone is not showing up IMEI, actually nothing when I type *#06# in dial
that mean you lost imei ....flash factory firmware by yourself...it will do the trick

Can you explain me which one I need ? What about bootloader, is it the same ? I've checked thread about bootloader and mine is "carrier firmware", not unlocked.
Which career search for career. Look at the build number in abiut and search for that.
I'm using ATT and my phone was locked on Sprint, so I flashed Sprint firmware and It's the same. I put the SIM card in, it did ATT setup and all of the apps from carrier but it's still block sign instead of signal sign in top right corner and airplane mode is light blue (not usual blue like when you turn it on)
At least this time it's showing up imei in dialer
I couldn't find ATT firmware, if someone knows there's my build number in first post.
